Problems solved by technology

[0003] At present, there are no automobile companies in China that manufacture active stabilizer bar systems, and they do not have the ability to independently develop them. The stabilizer bars of domestic cars are generally passive, and the ability of this type of stabilizer bar in anti-roll is very limited, especially for For

Embodiment Construction

[0046] In this embodiment, a control system of an electric active stabilizer bar such as figure 1 As shown, including: control unit, gyro sensor, rotor position sensor, current sensor;

[0047] The control unit includes: attitude detection circuit, motor rotor position signal processing circuit, current sampling circuit, motor vector drive and overcurrent protection circuit, main control chip;

[0048] The attitude detection circuit obtains the body attitude signal of the vehicle through the gyroscope sensor and provides it to the main control chip;

[0049] The rotor position sensor obtains the rotor position signal of the DC brushless motor and provides it to the motor rotor position signal processing circuit;

[0050] The current sensor obtains the three-phase current of the DC brushless motor and provides it to the current sampling circuit;

[0051] Motor rotor position signal processing circuit such as figure 2As shown, the rotor position signal is subjected to photoe...

Abstract

The invention discloses a control system and method of an electric active stabilizing rod. The control system is characterized by comprising a control unit, a gyroscope sensor, a rotor position sensor and a current sensor; the control unit comprises an attitude detection circuit, a motor rotor position signal processing circuit, a current sampling circuit, a motor vector drive and overcurrent protection circuit and a master control chip. The sidesway angle of a vehicle can be controlled in real time, and therefore during vehicle high-speed steering, the driving safety and taking comfort of the vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a control system and a control method for an electric active stabilizer bar. Background technique [0002] With the continuous increase of vehicle speed, people have put forward higher and higher requirements for vehicle ride comfort and safety, but conventional passive suspensions with passive stabilizer bars are difficult to satisfy ride comfort and handling stability at the same time In addition, it is impossible to adjust the roll angle stiffness of the suspension in real time. When turning at high speed, the vehicle is prone to roll, and excessive roll will easily cause fatigue and insecurity to the driver. Therefore, the research on vehicle active anti-roll control is one of the hot research issues in the automotive field. [0003] At present, there are no automobile companies in China that manufacture active stabilizer bar systems, and they do not have the...
